文摘

Hollow activated carbon fibers (HACFs) are prepared from biomass waste willow catkins. The HACFs possess high microporous specific surface area(1067 m2 g−1) with concentrated pore size distribution and rich heteroatom-doped functional groups. The HACFs-based electrode exhibit excellent electrochemical properties of high specific capacitance, considerable rate capability and high energy density.
